Dr. Omalu acknowledges that HBOT can help late effects of concussion

NEW ORLEANS - At the age of 15, Dr. Bennet Omalu made history by going to medical school. Then he made history again with his research. Now the movie "Concussion" takes on the controversy about his research and the potential dangers of playing contact sports.

Dr. Omalu, played by actor Will Smith in 'Concussion,' was the first doctor to discover, diagnose and name a chronic brain disease called chronic traumatic encephalopathy or CTE. It's found most often in football players, professional hockey players, and wrestlers.

He says taking regular fish oil can help the brain and hyperbaric oxygen treatment can help surviving neurons function better, but there is no cure. For now, the brain damage is permanent.
